To all whom it may concern." f Be it known that I, HARRY A; Hone, acitizen of the'United'States of America, residin in Altoona, in thecounty of Blair V Equalizing Arrangements for Locomotives, ofwhichthefollo'win is a true and exact Lisa i "description, referenceTJBing had to the accompanying drawings, which iorm a part 1 thereof.

My present invention relates to locomoportions of the weight thelocomotive transmitted to the leading truckandto. the drivers, andtrailing truck if employed,- of. {the locomotive. under varyingconditions'of' goperation. -Heretofo're it has-been the umversal prac v.25.

springs, etc'., transmitting the'load to the I driving. wheels andtrailing truckwheels on- -.eac11 side of the locomotive. Thus the body..--of-,.the. locomotive is carried by a threepoint support? systemofequalization.

it, the improper reduction in the weight imposed upon the truckoccasionally occurring as refererd to, above sometimes results inderailing the truck.

The arrangement disclosed and claimed herein compnses satisfactoryprovisions for impressing its proper "proportion of the weight of thelocomotive'upon the leading truck under all normal conditions bf operation and thus eliminates one source of accident. w

The various features of novelty which characterize my invention arepointed out with articularity inthe claim 'aniiexed to and orming" apart'of this specification. For a better understanding of the invention,however, and of the advantages possessed by it," reference should be hadto the accompanying drawings and d escriptive matter in which I- hav'eillustrz.
